You want one small fish for every 10 gallons. Small fish are clowns (maroons not included because they get huge), gobies, blennies, cardinals, dwarf angels. Big fish, like tangs or eels, (basically anything that gets bigger than 6 inches) i could as multiple fish. Tangs are usually two fish in my mind, eels are generally 3 or 4 because they get very long and they are very messy fish (they poop more than their fare share).
